   =head1 OVERVIEW
   
   Authors can only write-access the C</~authorname/> space. They can
   copy resources into the resource area through the publication step,
   and move them back through a recover step. Authors do not have direct
   write-access to their resource space.
   
   During the publication step, several events will be
   triggered. Metadata is gathered, where a wizard manages default
   entries on a hierarchical per-directory base: The wizard imports the
   metadata (including access privileges and royalty information) from
   the most recent published resource in the current directory, and if
   that is not available, from the next directory above, etc. The Network
   keeps all previous versions of a resource and makes them available by
   an explicit version number, which is inserted between the file name
   and extension, for example C<foo.2.html>, while the most recent
   version does not carry a version number (C<foo.html>). Servers
   subscribing to a changed resource are notified that a new version is
   available.
